How deep is the original tread? d220s

Got a K3 that's done about 8500miles, mostly upright commuting from when the Mrs had it.

Looked at the front tyre a bit more closely the other day and the central grooves seem a bit shallow.
Stuck a key in and had a quick measure. - about 2.5mm.

What's the original depth?

ie
How worn is it?

Back's about the same

The edges are untouched

Time for new rubber?

Legal minimum is 1mm accorss 75% of the tyre, so you can run them a bit longer if needed, They're going to be getting past their best though, have a look in the tyres section for some good replacement options

New tyres come out of the tyre factory with around 7mm tread iirc, possibly 8mm.

Guess they're pretty worn then

Time to consult the piggy bank

Dont break the bank mate, Ive got a set of practically brand new original tyres only done maybe 200 miles at the most. If your interested we can come to an agreement

2.5 mm, on them tyres theres plenty of mileage left, i let my dunlop qualifiers get complety bald in the middle before i replaced them today, still werent illegal either.....

Tyres have a strange habit of getting through the last few mm much quicker than expected. I had at least 2mm when I set off for the Norf/Sarf - after 250 miles of mainly motorway riding on the way up there they were looking very sad. By the time I got back home (another 650 miles or so) they were completely shagged

thats nearly 1000 miles though, and the heat going into the centres through motorway riding, what you expect?
